MACHINE FOR MAKING BOX PARTS Filed May 15, 1934 7 Sheets-Sheet 7 Patented June 2, 1936 UNITED STATES PATENT OFFICE 93 Claims. (01. 93-49) This invention relates to machines for making box-parts or similar articles from such material as pasteboard, being especially concerned with the setting-up of blanks into boxand cover-form. It is an object of the invention to simplify the construction and manner of operation of such machines and to increase the efiiciency of the setting-up mechcanisms and their associated elements.

A feature of the invention by which this object is gained consists in the direct association of boxand cover-settingup mechanisms upon the same frame and their actuation by mechanism common to both. This common actuation also preferably extends to mechanism by which the blanks are advanced to and removed from the setting-up mechanisms. Set-up or wall-boxes, as those used for marketing pairs of shoes, are always furnished with covers, and the present organization supplies "a box and its cover simultaneously, so the two may be assembled immediately ready for shipment, handling of the box-parts being minimized. The number of machine elements is also reduced, as compared with independent settingup mechanisms, as is the floor-space occupied.

Another feature of the invention, which is applicable as well to the manufacture of either boxes or covers separately, involves operations upon blanks at successive stations. At these stations, I

the second form. Sin e less time is required for i the folding operations at the second station than atthe first, the duration of pressure may be increased at the former and the adhesion of the .end-formations made more certain. The operation at different levels renders the transfer more ments; with improved means for mounting and actuating folding walls which co-operate with a form; with the actuation of the pressure members which co-operate with the forms,.this being accomplished by simple rugged mechanism absorbing relatively little power; with blank-supporting members which also perform an additional blank-folding function; with novel releasable means for permitting the abutment-plates co-operating with the forms to yield if clogging occurs, thereby preventing breakage; and with compact mechanism for advancing blanks at different positions and for locating the blanks at one of said positions.

The accompanying drawings illustrate. a particular embodiment of the invention,

Fig. 6 illustrates in broken perspective elements sections S and T, respectively, which are situated A boxside by side upon a frame Ill (Fig. 1). blank B which is to be formed by the apparatus appears is Fig. 9, the two lower positions showing it in its unfolded relation. It may be as disclosed in Letters Patent of the United States No. 1,811,135, dated June 23, 1931. It consists of a layer of pasteboard or other shell-material and such covering and stay-material as may be desired, having a rectangular portion or bottom a from which project pairs of opposite side-wings b, b and intermediate end-wings c, c. The opposite extremities of the side-wings carry comerlaps d, d, while the end-wings are provided with extensions e, e. The meeting lines of all these parts are defined by creases I to facilitate bending. The cover-blanks are not shown prior to the action of the apparatus upon them, but one appears as folded at C in Fig. 3 of the drawings. They have the same parts as just described for the boxblank, though the dimensions are different and the comer-laps preferably are without the denticulated ends appearing in Fig. 9. In each section of the apparatus the blanks are supported upon sets of rails l2, l2, with the end-wings at the opposite sides, and are delivered to the operating m at definite intervals by some such forwarding device as constantly traveling lugged chains l4, which deliver them between edge-gages i6, II at the first of two pairs of setting-up stations U and V, the latter being located upon a higher level than the former. To correctly arrange the blanks in both sections S and T for the first operation upon them, the edges of the leading side-wings are urged against stop-bars ll (Fig. 2), carried by the frame. This is effected by fingers 20, 20, one of which is pivoted upon the entering side of each station U and is joined by a link 22 to a lever 24 pivoted upon the frame and carrying a roll 26. Each roll is situated within a cam-track formed in one face of one of two disks 28, 28 (Fig. 1) fast upon a shaft Ill journaled transversely on the main frame. Power is applied to this shaft, and to the apparatus generally, from a motor 32 through gearing 34. The fingers are so actuated by the cams that as the blanks are delivered at the stations U with their forward edges'in proximity to the stop-bars Iii, these fingers are lowered to leave the paths of advance unobstructed, then they rise 'into contact with the rear edges of the blanks and dwell momentarily to guard against rebound from the stops. Following this, they descend to their initial positions.

The setting-up operations may now be considered, it being assumed that before reaching the present apparatus each blank will have had applied to it some such adhesive as glue, which is to secure the opposite end-formations. Preferably, the coating will be upon the inner surfaces of the end-wings c with which the comer-laps d are to contact, and upon the inner surfaces of the endwing-extensions e which are to be secured to the comer-laps. In each of the sections S and T, the operations and the elements bywhich theyare performed may be substantially the same, said elements differing chiefly in size and contour. Consequently, but one of each pair of the stations U and V will generally be described. At a station U is done all the folding of the sideand endwings and of the comer-laps of either a box or a cover, there being left unfolded only the end-wingextensions. At this first station there is also applied pressure to effect the preliminary setting of the end-formations, which is later perfected at the succeeding station V. Each blank is received above a form 40 (Figs. 4 and 6) about which the folding is to be done. This form may consist of an integral casting cored out for the sake of lightness. It is carried upon two vertical spindles 42, 42, and to permit it to yield, for reasons which will later appear, it is mounted to move laterally upon its spindles. For this purpose .there is threaded into the upper extremity of each spindle 42 a stud 44 having a reduced end 46. A hexagonal portion 48 of the stud bears upon a yoke joining the spindles 42. and when rotated serves to draw together tapered surfaces at 52 upon the yoke and spindles to secure these elements to each other. Surrounding the end 46 of each stud is a sleeve 84, resting upon the hexagonal portion 4! and fixed in place by a nut 56 threaded upon the top of the stud-end. Sure rounding and spaced from this sleeve is a second sleeve 58, supported upon a shoulder 60 at the bottom of a vertical bore in the form 40. The sleeve SI is held down upon the shoulder by a cap 62 threaded into the upper end of the bore. At 64, between the sleeves 54 and 58, is interposed some such yieldable material as rubber, this preferably being vulcanized to both sleeves. It will be seen that the form 4| is free to be displaced in all di-, rections to an extent determined by the yieldability of the material 04.

Each pair of spindles 42 carrying a form 40 are guided in the frame and secured near their lower extremities is a lower yoke 66 (Fig.2). Articulated to a lateral extension from this yoke is a link 68 which, at its lower end, is similarly joined to a lever 10 fulcrumed upon a spindle H and provided with a roll I2 lying within a cam-groove in one side of a disk 14. As appears'in Fig. 2, the fulcrum-portion of the lever 10 is extended laterally to give two bearings, so it may better resist lateral thrust. The disk for each of the forms of sections S and T is fixed upon one of two shafts 16, I6 joumaled at opposite sides of the frame and extending longitudinally thereof. These shafts are driven by bevel-gearing l8. 18 from the transverse shaft 30. By its cam, each form is moved between a lowered position in which it receives a blank above its upper surface, as already described, into co-operation with elements by which the wings and corner-lapsof the blank are to be folded and with other elements which apply pressure to the end-formations.

Referring particularly to Fig. 6, the sidewings I) of each blank B are brought, by the elevation of the form, from the dotted-line position into contact with curved faces 80 upon walls 82, 82. These walls are arranged to be moved in to prevent the blank from bulging outwardly when pressure is applied to its ends. For this purpose, each wall is attached to spindles 84, 84, guided in horizontal sleeves 86 fixed to the frame (Fig. 4). One side of each spindle has rackteeth with which meshes a gear-segment 88 extending through a slot in the sleeve and fast upon one of two transverse shafts 90, 90 (Figs. 2 and 8) rotatable upon'the frame at the rear and front of the forms 40. A spring 92 is interposed between the end of each sleeve and a nut 94 threaded upon the end of its spindle. This takes up back-lash in the gearing. Above the rearward shaft 90 is Journaled a shaft 96, which is joined to both of said shafts 90 by pairs of arms 98 and intermediate links I00. An arm I02 upon the shaft 96 is linked at I04 to a lever I06 provided with a roll I08 operating in a cam-groove in a disk III upon the shaft 30 (Fig. 1). The connections of the links ")0 to the arms 98 on the shaft 98 are preferably through springs ill to permit the actuating force to be applied yieldably to the walls 82.

As the side-wings b of the blank are being folded to vertical positions over the rising form by contact with the wall-surfaces 80, the corner-laps d are also being bent inwardly upon the sidewings by engagement with normally stationary folding members I it, which are adjustably carried upon the frame outside each of the four corners of the form. As appears in Figs. 4 and 6. each member 6 is secured to a vertical spindle H8.

Each spindle is mounted upon a bracket I20, provided with a screw I22 to allow the spindle to be variably clamped vertically and angularly about its'longitudinal axis. The bracket is shown is secured to the. frame by a slot-and-screw connection I24, so the member II6 may be adjusted in all directions horizontally. By this mounting means the time of folding of the corner-laps by surfaces I25 of the members I I5 may be effected in the best relation to that of the side-wings.

Surfaces I30 upon opposite members I32 and I34 situated at the ends of the walls 82, 82, by

engagement with the end-wings c of the blanks, fold these wings outside the corner-laps, bringing the parts to the full-line position of Fig. 6. These members I32 and I34 later apply pressure to the end-formations. Considering Figs. 1, 2, 3 and 4, each form 40 has at its inner extremity, or that toward the center of the frame, the stationary abutment-assembly I32, I32, while at the outer end is the movable head I34. This head is arranged to travel horizontally in ways in the frame and has at its outer side a central surface I36 inclined outwardly and upwardly. At each side of this surface is a rack I40, both racks being inclined similarly to the central surface. Spaced from this end of the head is an abutment I42 having a surface and racks corresponding to and horizontally alined with those of the head, but being vertical rather than inclined. Midway between the head I34 and abutment I42 is a vertically movable actuating member I44 at each side of which the vertical surface and rack-formation are repeated. interposed between each side of the actuating member and the abutment and head is a roll I46 contacting with the surfaces I36 and pinions I40 formed upon the roll and meshing with the racks I40. The actuating member I44 has passing through it a vertical spindle I50, which at its lower extremity has a terminal piece I52 guided in its movement by a link I54 joining it pivotally to the frame. Each terminal has rotatable upon it a roll I55 lying in a cam-groove in a disk I58 upon one of the shafts 16. The member I44 is sup ported upon a sleeve I60 (Fig. 2) surrounding the spindle and resting upon a spring I62 and a collar I64 threaded upon said spindle. When the forms 40 bearing the blanks with the wings and comerlaps folded arrive at the highest point in their upward travel, their ends register with the heads I34, the walls 32 having been moved in by their actuating mechanism to hold the sides of the blanks closely against the form.- The cams thereupon raise the actuating members I44, which carry with them, through the gearing I40, I48, the rolls I46. Because of the inclination of the head-surfaces I36, a wedging effect is produced, and both heads I34 are forced against the endformations of the partially set-up blanks, causing the preliminary adhesion of the end-wings to the corner-laps because of the glue which is upon the former. In this action, the cylindrical rolls transmit the pressure, the diameter of the pinions I48 being such that, without lateral compression, they are caused to travel with the members I44 and thus produce the wedging effect and consequent pressure applied by the heads I34 to the outer ends of the box. This, in turn, urges the opposite end of the form against that portion of the box and the latter against the fixed abutment I32. The slight displacement of the form is permitted by the yleldability of the mounting 64. This ,mounting also allows the form to yield in any direction horizontally, tend- -sion of the springs.

- frame.

ing to prevent breakage if an excessive thickness of theblank-inaterial is introduced between the pressure-applying surfaces. To return each head to'its normai relation upon the descent of the actuating member I44 from the active position, there are connected to opposite outward extensions I66, I66 from said head rods I61 passing through openings in the abutment I42.

Springs I68 surround these rods, exerting their expansive force upon the abutment and upon nuts I69 on the threaded ends of the rods. this simple and durable pressure mechanism, an adequate force may be exerted and frictional resistance minimized. Since the force is applied through the springs I62, it is limited by the compressibility of -these springs, and this may be varied by changing the position of the collars I64 and therefore the normal degree of compres- The friction resisting the movement of the actuating members I44 is made not only small by the presence of the rolls I45 but also substantially constant. Thus, for any particular adjustment of the springs I62, the same pressure will be applied to all blanks operated upon.

Situated above and parallel to the top of each form 40 is an abutment-plate I10 secured to the lower extremity of a spindle I12. At their upper ends the spindles of the two stations U, U are attached to a common top-girt or carrier I14 (Fig. 3), which is supported upon a central vertical spindle I16 arranged to reciprocate in the An arm I18 (Fig. 2) projects from one side of the spindle I16 and a link I joins this to a lever I32 fulcrumed upon the frame. Upon this lever turns a roll I84 acted upon by a camgroove in the disk IIO upon the shaft 30. The movement imparted to each plate by the cam is such that it is initially separated from the form with which it registers to permit the reception of a blank, the width of this space being sufficiently narrow to hold the blank against excessive curvature, which would prevent it from properly engaging the stop I8. Then the plate is lowered into close proximity to the blank, retaining this against upward displacement upon the form during the elevation of the latter, the plate and form moving together, the plate maintaining this relation during the application of v lugs I88, I88 on the top-girt. This holds the spindle and plate against rotation. At the opposite end, the arm has a depression to receive a plunger I99 backed by a spring contained in a holder I92 pivoted upon the top-girt. Under normal operating conditions, the'plungcr holdstheplate against movement upon the top-girt, but in event of the interpositionof an abnormal thickness of material between the form and plate,

the plunger yields against its spring so the plate may rise to relieve the strain-upon it. By swinging the holder I92 upon its pivot the plunger may be shifted from above the cross-arm, and the spindle and plate may be lifted freely to give full access to the form and associated elements.

The above-mentioned transfer of the blanks from stations U to stations V is accomplished for each operating section 8 and T by a stripper 266 normally resting in a recess in the top of each form 46. This stripper is shown in Fig. 6 as a skeleton plate and is mounted upon the upper end of a spindle 262 passing through an opening in the form-yoke 66. A yoke 263, guided by the spindles 42, is secured to the spindle 262 and has an extension opposite that of the yoke 66 and which is connected by a link 264 to a lever 266 fulcrumed upon the frame, with a roll 266 acted upon by a cam-groove in one face of a disk 2i6 rotated by one of the shafts 16. The

control exercised by the cam over the stripper causes it to rise with the form in the recess during the blank-folding and to remain in said recess while the pressure is applied. 'When the operations upon the blank at each station U are completed and the form descends to its initial position, the stripper is elevated so the partly folded blank is separated from said form and is carried up to the level of station V. Supporting means for the blank coming into action at this upper level, the stripper descends, resuming its place in the form-recess for action upon the succeeding blank.

The blank-supporting means at stations V is most clearly shown in Fig. 5. Guided one above the other to slide side by side at the rear of the stations U and at the level of stations V are two carrier-rods 2l2, 2l2. Clamped to each rod for adjustment longitudinally thereof are two blocks 2, one for each station V. Attached to the blocks by slot-and-screw connections 2l6 are supporting arms 2i 6, a pair of arms upon differ ent rods being at opposite sides of each station V, The forward extremity of e h arm is guided by sliding engagement at 226 th rearward extensions 222 from opposite pressure-walls 224, which act upon the folded blanks at stations V to apply final setting pressure. Each arm has at its inner face a horizontal supporting surface 226. While the stripper 266 at each station V holds the creases 1 between the end-wings c and their extensions 2 just above the surfaces 226, the rods 2i2 are moved in opposite directions to force thearms 2i6 against the extensions so these are turned inwardly substantially atright angles to the end-wings, they now resting upon the arm surfaces 226. This rod-movement is produced by levers 226 (Fig. 2) fulcrumed at opposite" sides of the frame and pivotally joined to the opposite extremities of therespective rods; Each lever has a roll 236 lyingin a cam-groove in the inner face of one of the disks'2i6; The top-plate 116 is still above the form in close proximity. to the blank, preventing this from being upwardly d1 placed. In preparation for the forward movement of the blank into the final operating portion of station V, the stripper-plate is lowered by its cam. The step of transferring the blank for folding the end-wing-extensions and applying a final setting pressure will now be described.

Again referring to Fig. 5, and also to Fig. 2, .journaled in blocks 23i, capable of some vertical movement at the top of the frame, is a carriershaft 262 having the portion between its ends square in section. Upon this squared portion,

clamped for adjustment longitudinally thereof to correspond to the length of the blanks being operated upon, is a pair of arms 234, 234 for each station V. The lower end of each arm has secured to it a contact member 236, which has a lateral inward extension 231 normally lying just at the rear of the blank when this is elevated tus,- being carried away, trated conveyor. As each blank is advanced by 262, after the fin-. ished box-parts have passed beyond ;them, are

216.- They stop ..the

as just outlined. A vertical surface 236 on the I member 236 holds the blank centered between the arms 2". Each arm 234 is joined by a link 236 to a slide 246 movable in ways in a guide member 242 projecting forwardly from one of the pressure-walls 224. The opposite slides of each station are shown as connected by a'tie-rod 244, and upon the ends of this rod, outside the slides, are pivoted, Pushing fingers 246 limited in their downward movement but free to turn upwardly about their pivots. The shaft 232 is oscillated by an-arm 246 fast portion and united by a link 246 tothe frame to form a toggle. This link is joined by a second link 256 to a lever 252, fulcrumed on the frame and provided with a roll 264 entering a camgroove in a disk 266 upon the shaft 36. As the shaft 232 is thus oscillated, a linkage 266 (Fig. 3) connecting to the frame the opposite end to that bearing the arm 246 maintains said shaft horizontal as it rises and falls. Arranged to turn upon the frame in front of the arms 234 is a transverse horizontal shaft 266, to which are secured downwardly curved stop-fingers 262 movable into and out of the paths of the blanks as' they are advanced into the forward operating portion of the stations V. The shaft 266 has an upwardly extending arm 264, articulated to which is a link 266 slotted at its opposite extremity and there guided by the pivot of the link 246. Projecting from one side of the link 266 is a roll 266 operating in a cam-groove formed in a forward extension 216 from the link 246. The effect of this transferring mechanism as actuated by the cam-disk 256 is as follows: The blank having been freed by the descent of the form, the extensions 231 of the contact members 236 first move into engagement with the rear of the partly formed boxand cover at the junctures of the bodies a and side-walls b. The members 266 then travel forward in practically rectilinear paths, moving the blanks over the surfaces 226 and on to alined horizontal surfaces 212 upon; the

ejected from the apparaif desired, by an unillus- Thus the box-parts are the members 236, the fingers lowered by the cam-arm blanks upon the surfaces 212 in thecorrect position for the final operation and there temporarily hold them. As the transferring elements return to their initial positions, the fingers 245 'yield upwardly upon their pivots, moving over the tops of the box-parts which have just been advanced,- without displacing them. I

A sectional form F, which at each station V folds in the glued end-wing-extensions e against the surfaces of the comer-laps, is illustrated in detail in Fig. 7. The body 266 of the form is of inverted U-shape with the ends open, and movable through these openings are expansible endsections 262, 262 resting upon a base 264 supporting the body. Vertical spindles 266, 266 carry the base, and these are united by connections similar to those for the form 46 at each station U, said connections terminating in a roll 266 lying in a cam-groove in the face of the disk 14 opposite that which actuates said form 49. Passing through an opening at the center of the base 284 is a spindle 299, having fast to its upper ex-. tremity a head 292 each end of which is pivotally joined by a link 294 to one of the form-ends 282. The spindle 299 is raised and lowered by connections generally resembling those for the stripper 299 ateach station U, and including a roll 296 received by a cam-groove in the inner face of a disk 298 upon one of the shafts 16. It will be evident that as the spindle 299 is raised and lowered relatively to the form-spindles 286, the elements 292 and 294 act as toggles, expanding and contracting the form longitudinally. The spindle 299, in addition to the head 292, has secured to it below and extending outside the head a block or spacer 399, which normally lies out of contact with the end-sections 282, 282. An

enlargement 39 2 of this spacer is situated just below opposed inner ends at the bottom of the sections, while another enlargement 394 is similarly related to the upper portions of the sections. The action of this spacer will now be described in connection with the general operation at stations V.

From its normal lowered position and with the end-sections drawn in, each form F is elevated by its spindles 286 under the influence of the cam 14 and enters between the walls of the folded blank, which is resting upon the surfaces 212. In this movement, the form engages the end-wing-extensions e, e which are now substantially horizontal and forces them up between the walls of the box-part and toward the corner-laps d. At this time, the body-portion a. of the blank is just below the guides 242, which hold said blank against upward displacement. As the form approaches its highest position at which it lies fully within the walls, the spindle 299 is raised by the cam 298, more rapidly than the spindles 286, from its normal position in which the toggle-connections to the sections 282 are broken downwardly. As the toggles are thus straightened to carry the form-sections 282 against the end-wing-extensons, the pressure members 224'are simultaneously moved inwardly against the end-walls 0. Although the same reference-character 224 has been applied to each of these pressure-walls included in stations V, they are preferably arranged in pairs of fixed and movable elements, as already described in connection with stations U, and may be acted upon in the same manner. The similarity of the mechanisms may clearly be seen in Fig. 4 and no further description thereof is considered necessary. The actuation of each of the movable walls at each of the stations V is effected by a cam-disk 396 upon one of the shafts 16. After the toggle members have been fully straightened, upward travel of the head 292 continues slightly past the center. At this time the enlargements 392 and 394 have been brought between the pairs of opposed walls upon the formsections-282, and when the toggles break upwardly these walls engage both spacer-enlargements, locking the sections against further approach to each other and removing all strain from the toggles as the final pressure is applied by the walls 224. It is not necessary in this case to yieldably mount the forms F upon their spindles, since the greater length of said spindles at stations V give.

all the lateral yield necessary. It is to be observed that because the other operations than applying of pressure take less time at stations V than at stations U, the end-setting forces at the latter may be longer continued and secure attachment by adhesion insured. At the terminationof the pressure-period the walls 224 release each box-part and its form, and the toggles are broken downwardly to cause the contraction of said form,

which is then lowered to its initial position, leav-' 5 ing the finished box-part resting upon the wallsurfaces 212. After the last action of the apparatus, the fingers 245 are advanced to eject the box and. cover over the extension-surfaces 214, at the same time the preceding blank is being posi- 10 tioned over the forms F by the members 236 and the stop-fingers 262.

A brief outline of the operation of the apparatus will now be given, especially with reference to the successive operating steps, as illustrated 15 in Fig. 9 of the drawings. In that figure, a boxblank B is shown at K as it approaches the setting-up mechanism of section S upon the rails I2 under the influence of the lugged feedchains I4. A cover-blank is simultaneously be- 29 ing delivered to the setting-up section T. In each instance, the blanks will have received from mechanism not herein disclosed a coating of an adhesive over the appropriate areas of the end-wings and their extensions. They are 25 brought to rest in the proper position L upon the tops of the forms 49 at stations U'by the stops I8, rebound being prevented by the fingers 29 which rise behind them. Now the forms ascend, the blanks being retained against upward 30 displacement by the abutment-plates I19 which are traveling at the same rate as the forms. Thus the side-wings b, corner-laps d and endwln'gs c are brought successively into engagement with the respective members 82, I16 and 95 I32 and I34, which fold them into box-shape about the forms, save only the end-wing-extensions e. The manner in which the folding is effected may be seen in part at positions M and N. Following the folding, pressure is applied for 40 a brief time by the members I32 and I34, as appears at O. This is suflicient to at least insure temporary adhesion of the corner-laps to the end-wings. Upon withdrawal of the members I34, the strippers 299 with the plates I19, rise 45 and the forms 49 descend to their initial positions, the blanks being thus separated from said forms. The upward movement of the strippers with the blanks continues until the upper level at stations V is reached, as appears at P. There- 5 upon, the arms 2I8, 2I8 of the two pairs between which the partially folded blanks are now located approach each other, contacting with the end-wing-extensions e, so they are bent in horizontally. Following this, the strippers descend, 55 leaving the boxand cover-blanks supported upon the arm-surfaces 226. The advancing, locating and discharging mechanisms now come into action, they operating in definite timed relation, the members 236 advancing the blanks 60 just referred to from the arm-surfaces 226 to position Q upon the alined surfaces 212 on the pressure members 224. At the same time, the members 245, actuated in common with the members 236, discharge from the apparatus the preceding box and cover which have been completed. As the blanks arrive upon the surfaces 212, the stop-fingers 262 are lowered by the common actuating means, so the folded blanks are correctly located above the forms F. The blanks are at this time in the final operating position at stations V. The arms 2I8 may now return to their normal separated relation, and the plates I19 are lowered into co-operation with the depressed forms 49. with their secrespectively.

tions 202 retracted, the forms F rise, contacting with the horizontally bent end-wing-extensions and forcing these upwardly and outwardly as the forms enter the folded blanks. Once fully within the blanks, the form-sections 282 are expanded to carry the end-wing-extensions against the corner-laps. and the members 22! move in and apply final setting pressure to the completed end-formations. This step in the setting-up operations appears at R in Fig. 9. This is not a separate position, but would, in fact, coincide with the position Q, being removed horizontally therefrom to better illustrate the relation of the elements. The duration of this final pressure, on account of the less time consumed in the folding and transferring operations at stations V as compared with those at stations U, may be for a greater portion of a cycle, so firm adhesion may be obtained. As the delivering members 236 and discharging members 245 return to their normal positions after their active movement as just described, the fingers 262 are raised, and upon the next stroke of the members the completed box and cover are ejected, the formsections 282 having been retracted and the forms F lowered, leaving the box and cover upon the surfaces 212 for discharge over the surfaces 214. It will be appreciated that occupying a relatively small floor-space and with a reduced number of actuating elements, my improved setting-up apparatus produces simultaneously both a box and its cover, delivering these together for immediate closing and packaging. The amount of handling necessary is therefore minimized and the cost or production reduced.
